[Live-devel] MPEG4 elementary video

[Scott Hays]

Hello,
I'm trying to stream MPEG4 elementary stream video over RTP.  Using 
testMPEG4VideoStreamer and openRTSP with the "-n" option, I get:

<=====================>
Opened URL "rtsp://192.168.1.111:8554/testStream", returning a SDP 
description:

Created receiver for "video/MP4V-ES" subsession (client ports 18888-18889)
Setup "video/MP4V-ES" subsession (client ports 18888-18889)
Created output file: "video-MP4V-ES-1"
Started playing session
Receiving streamed data (signal with "kill -HUP 4625" or "kill -USR1 4625" to 
terminate)...

<========================>

The output file, video-MP4V-ES-1, is empty.  Reading the mailing list 
archives, I'm guessing that at least one problem is that the MPEG4 video 
doesn't have visual object sequence headers, since the SDP description 
doesn't have a config line.  When I've tried streaming this file using 
ffserver, it has complained about the file lacking "headers" as well.  Is 
there anything else which might be giving me a problem, i.e. something else I 
should be looking at as well as the VS header issue?  Or is this probably it?
